Archäologisches Freilichtmuseum Funkenburg, Archaeological open-air museum and castle site in Westgreußen, Germany.

The Funkenburg Archaeological Open-Air Museum is a partial reconstruction of a Germanic fortified settlement on a flat spur that drops steeply on three sides at the edge of Westgreußen. Since 1992, walls, ditches, towers and palisades have been rebuilt on the original site, with reconstructed dwellings and workshops in the main enclosure.

Archaeological excavations conducted between 1974 and 1980 revealed this fortified Germanic settlement was inhabited from the 2nd century BCE to the early 1st century CE, with evidence of approximately 60 huts and around 500 pit features discovered during investigations.

The museum demonstrates Germanic daily life through reconstructed longhouses, pit houses, and storage buildings, showcasing traditional construction techniques using local materials like wood, clay, and turf while illustrating the social organization of ancient tribal communities.

The museum operates Wednesday through Friday from 10:00 to 17:00 and weekends from 12:00 to 17:00, with admission fees of €4.00 for adults, €2.50 for reduced tickets, and €2.00 for children aged 6-12, though wheelchair accessibility remains limited.

The site became a centre for experimental archaeology in Thuringia from the early 1990s, alongside the pottery workshop at Haarhausen. Club members in period dress demonstrate Iron Age crafts such as potting, spinning, dyeing, weaving, netting and archery, and an annual Funkenburg festival is held in August.
